Bearing arrangement

Abstract

A bearing arrangement includes a bearing for rotatably supporting a journal of a roller in a rolling mill stand, and a bearing support body with a bore for receiving the bearing. The profile of the bore in the unstressed bearing support body is configured, at least approximately, according to the negated pre-calculated profile of the bore under a load.

1. A bearing arrangement ( 100 ), comprising:
 a bearing ( 110 ) for rotatably supporting a journal ( 210 ) of a roll ( 200 ) in a rolling mill stand; and 
 a bearing support body ( 120 ) having a bore for receiving the bearing, 
 
       wherein a profile (K) of the bore in the unloaded bearing support body is formed at least approximately according to a negated profile of the bore at a pre-calculated load of the bearing support body, 
       characterized in that 
       the bore in the bearing support body ( 120 ) is formed of conical bores following sectionwise one another and linearly continuously. 
     
     
       2. A bearing arrangement ( 100 ) according to  claim 1 ,
 characterized in that 
 the bore in unloaded bearing support body is formed rotationally symmetrically convex. 
 
     
     
       3. A bearing arrangement ( 100 ) according to  claim 1 ,
 characterized in that 
 the bore in the unloaded bearing support body is formed rotationally symmetrically concave. 
 
     
     
       4. A bearing arrangement ( 100 ) according to  claim 1 ,
 characterized in that 
 the bearing ( 110 ) is formed as a slide bearing ( 110 -G) in form of a bearing bush for rotatably supporting the journal ( 210 ) of the roll ( 200 ), wherein a cylindrical lubrication gap ( 5 ) is formed between the bearing bush and the roll journal. 
 
     
     
       5. A bearing arrangement according to  claim 1 ,
 characterized in that 
 the bearing ( 110 ) is formed as a roller bearing for rotatably supporting the roll journal ( 210 ). 
 
     
     
       6. A bearing arrangement ( 100 ) according to  claim 1 ,
 characterized in that 
 the bearing support body ( 120 ) represents a housing for the bearing in form of a bearing chock that is connected with the rolling mill stand.
